The aim was to study the effect of artificially constructed consortia of microalgae-bacterial symbionts on growth and lipid production by Chlorella vulgaris (C. vulgaris), as well as the inter-relationship between microalgae and bacterial in a photoautotrophic system. The results showed that compared to an axenic culture of C. vulgaris, H1 co-culture system (axenic C. vulgaris-Stenotrophomona smaltophilia) had the strongest effect on the C. vulgaris growth. The biomass, specific growth rate and maximum productivity of C. vulgaris were increased by 21.9, 20.4, and 18%, respectively. The bacteria in co-culture system had a significant effect on the accumulation of lipid and fatty acid components of C. vulgaris: the content of lipid was increased by 8.2-33.83%, and the components of the saturated fatty acids and oleic acids also had an obvious improvement. The results indicate that the microalgae-bacterial co-culture system can improve microalgal biomass and the quality of biodiesel.
目的是研究人工构建的微藻-细菌共生体对小球藻（Chlorella vulgaris，C. vulgaris）生长和油脂生产的影响，以及在光自养系统中微藻和细菌之间的相互关系。结果表明，与小球藻的无菌培养相比，H1 共培养系统（无菌小球藻-嗜麦芽寡养单胞菌）对小球藻生长的影响最强。小球藻的生物量、比生长率和最大生产力分别提高了 21.9%、20.4%和 18%。共培养系统中的细菌对小球藻油脂和脂肪酸成分的积累有显著影响：油脂含量增加了 8.2-33.83%，饱和脂肪酸和油酸的成分也有明显改善。结果表明，微藻-细菌共培养系统可以提高微藻生物量和生物柴油的质量。
